The Fore system is tried and proven and does not need a BAP. There is another system that I've been looking at that uses Fore parts but is suppose to be plug and play..so to speak. That system is the 2.5 Triple Fuel System by Tapped Performance. It may be worth looking at their system as well.
The Fore system is beyond my expertise since I don't believe they come with step by step instructions. The Tapped system does come with instructions and doesn't require any cutting, it uses the factory plugs. Just another alternative to consider.
